2-channel 安卓隔离开关放大器 IM1-22EX-R 230VAC Edition说明书

The 2-channel isolating switching amplifier IM1-22EX-R/230VAC is equipped with intrinsi-cally safe input circuits.
Sensors according to EN 60947-5-6 (NAMUR)or potential-free contact makers can be con-nected to the device.
The output circuits feature 2 relays, each with 1 NO contact.
Six front panel switches are available to set the output mode separately for each channel (NO/NC mode), as well as to enable/disable wire-break (WB) and short-circuit (SC) moni-toring separately.
When using mechanical contacts, wire-break and short-circuit monitoring must be switched off or the contacts must be wired to resistors (II) (see circuit diagram).
The Pwr LED lights green to indicate opera-tional readiness. The 2-color LEDs 1 and 2below light yellow to indicate the switching status of the corresponding output. The same LEDs turn red in the event of an input circuit error, provided the input circuit monitoring function is switched on. Thereupon the asso-ciated output relay drops out.
